Ferry over from Detour to Island. I recommend parking at the trail staging area that comes into Detour and ride thru town to the docks, it is prretty self explainitory. It cost far less to bring sleds acrossed on Ferry then a truck and say 4 place trailer. Plus it is cool! Ride the Island will take most the day if you hit everything. I have started in Pellston road to the Mackinaw bridge took the shuttle Van/6 place trailer accross to St. Ignace and rode to Drummond via Cedarville, caught the ferry in Detour rode one lap around the island, went accross the ice off the North side of Drummond to St Joseph Island Ont. then on to Thessalon Ont. in a full day. 285 miles. Also done the same trip and went to Wawa on second day. (do not attempt wawa leg with Halfway haven being closed).
